The `require_wgpu_24` function accepts either a fully setup WGPU, or one
can configure individual aspects such as features/limits.
The wgpu_texture example uses this to add push constants to the required
features and thus eliminates the need for uniform buffers.
On macOS we should default to the Meta renderer, similar `renderer-skia` defaults to D3D on Windows. Unfortunately commit 0d36f88152 broke this by forgetting
that None with the requested graphics API means: Go for with what we have, nothing special requested.
This also fixes the terminal output "Failed to initialize Skia GPU renderer: Requested non-Metal rendering with Metal renderer . Falling back to software rendering" (and similar on Windows).
Based on API review, PlatformBuilder becomes BackendSelector with
a slightly smaller API surface but more options, such as selecting
Metal or Vulkan rendering.
Updated the version from 1.1 to 1.2
Renamed the header to "Slint Royalty-free Desktop, Mobile, and Web Applications License"
Added definition of "Mobile Application" and grant of right
Moved "Limitations" to 3rd section and "License Conditions - Attributions" to 2nd section
Added flexibility to choose between showing "MadeWithSlint" as a dialog/splash screen or on a public webpage
Moved the para on copyright notices to section under "Limitations"
Move this back out of render() again and make it stateful in the renderer. Reduces the amount of book-keeping required and it's always the same callback anyway.
This might fix the issue with resizing causing swapchain re-creation
errors, because "Swapchain creation no longer returns an error when the
swapchain extent doesn't match the current surface extent."

This doesn't require a windowing system, just Linux and Vulkan drivers
that supports the display extensions.
It's called linuxkms as soon this will go beyond Vulkan and also support
EGL and perhaps dumb buffers for software rendering.
